Around 1,000 mourners gathered in Dublin this morning for the funeral of campaigner Christine Buckley.
The congregation heard how amid the clamour of denial, a "tiny voice" won freedom and vindication for many others who had been abused.
Ms Buckley died in St Vincent's Hospital in Dublin on Tuesday, following a long battle with cancer.
She was the main subject of Dear Daughter, the 1996 RTÉ drama documentary that gave her account of life as a child in the Goldenbridge orphanage in Dublin, which was run by the Sisters of Mercy.
It created the first major controversy around institutional child abuse in the Catholic Church in Ireland.
Ms Buckley's story of brutality at the religious run orphanage, inspired a State apology to all who were abused while in care.
Today, President Michael D Higgins, Archbishop Diarmuid Martin and Minister for Health James Reilly joined thousands of people to celebrate her legacy.
Mourners heard how Ms Buckley represented the power of one against many and that her biggest legacy is that survivors are not just listened to but are believed.
The Aislinn Centre in Dublin, which was set up by Ms Buckley, continues to help victims of child abuse.
Mourners at today's funeral were requested to make any desired donations to a charity of their choice.
Ms Buckley is survived by her husband Donal and three grown-up children, Darragh, Conor and Cíona.
